Survey-weighted ordered logistic regression
Hi,
I am trying to fit a model with an ordered response variable (3 levels) and
13 predictor variables. The sample has complex survey design and I've used
'svydesign' command from the survey package to specify the sampling design.
After reading the manual of 'svyglm' command, I've found that you can fit a
logistic regression (binary response variable) by specifying the

Problem with ordered logistic regression using polr function.
Hi,
I'm trying to fit a ordered logistic regression. The response variable
(y) has three levels (0,1,2).
The command I've used is:
/ordlog<-polr(y~x1+x2+x3+x4, data=finalbase, subset=heard, weight=wt,
na.action=na.omit)
/
(There are no NA's in y but there are NA's in X's)
The error I'm getting is:

Lattice package par.settings/trellis.par.settings questions
Hi All,
I'm trying to modify some of the default graphic parameters in a
conditional histogram. While I was able to change the default grey
background to white, I couldn't change the axis.font or the xlab font.
I used the following code:

"vcov" error in svyby and svytable functions
Hi,
I'm trying to compute survey svytable statistic on subsets by using the
svyby function.
Here is the code:
b<-svyby(~V024+V751, by=~V025, design=strat2, svytable, round=TRUE)
The vars, V024, V751 and V025 are factors. The by var has 2 levels, and
hence there will be two subsets. strat2 is created by the svydesign function.
It's giving me the following error:

goodness of fit for logistic regression with survey package
I am making exploratory analyses on a complex survey data by using survey
package. Could you help me how to see the goodness of fit for the model
below? Should I use AIC, BIC, ROC, or what? What code would let me run a
goodness of fit test for the model? Here are my codes:

Error from termplot() with make.panel.svysmooth() for complex survey data
Greetings,
I am using library(survey) to analyze some complex sample data. After
fitting a model I tried to use termplot() with make.panel.svysmooth(), but
I received an error (see below).
Could someone help me interpret the error message so I can make the
necessary corrections? The make.panel.svysmooth() function seems to work
fine, and termplot() worked fine after I dropped the smoother.

multinomial logistic regression with survey data
Hello,
Is there a function/package that can do multinomial logistic
regression using survey weights, similar to "svymlogit" in Stata? It
appears that only "svyglm" function (which does not allow multinomial
response?) is available in the "survey" package.
Thank you!

Package survey: singularities in linear regression models
Hello,
I want to specify a linear regression model in which the metric outcome
is predicted by two factors and their interaction. glm() computes
effects for each factor level and the levels of the interaction. In the
case of singularities glm() displays "NA" for the corresponding
coefficients. However, svyglm() aborts with an error message. Is there a
possibility that svyglm()

Weighted Logistic Regressions using svyglm
I?m running some logistic regressions and I?ve been trying to include weights
in the equation. However, when I run the model, I get this warning message:
Here?s what it says: Warning message: In eval(expr, envir, enclos) :
non-integer #successes in a binomial glm!
I think it is because the weights are non-integer values.

Coding design with repeated measurements in the survey package
Dear all,
I'm working on a design with rotating panels. Each site is sampled every X year. Have a look at the code below the get an idea of the design. In reality the number of sites will be (much) higher.
However I'm not sure if I coded the design correctly in svydesign(). Can someone confirm that it is either correct or wrong? I've added the lmer() equivalent that I want to

survey package svystat objects from predict()
Hello,
I'm running R 2.14.1 on OS X (x86_64-apple-darwin9.8.0/x86_64 (64-bit)), with version 3.28 of Thomas Lumley's survey package. I was using predict() from svyglm(). E.g.:

SURVEY PREDICTED SEs: Problem
Hello R-list,
I'm attempting to migrate from Stata to R for my complex survey
work. It has been straight-forward so far except for the
following problem:
I have some code below, but first I'll describe the problem.
When I compute predicted logits from a logistic regression, the
standard errors of the predicted logits are way off (but the
predicted logits are fine). Furthermore, the

relative risk regression with survey data
I have been asked to look at options for doing relative risk regression
on some survey data. I have a binary DV and several predictor /
adjustment variables. In R, would this be as "simple" as using the
survey package to set up an appropriate design object and then running
svyglm with family=binomial(log) ? Any other suggestions for covariate
adjustment of relative risk

longitudinal survey data
Dear R-Users!
Is there a possibility in R to do analyze longitudinal survey data (repeated
measures in a survey)? I know that for longitudinal data I can use lme() to
incorporate the correlation structure within individual and I know that there is
the package survey for analyzing survey data. How can I combine both? I am
trying to calculate design-based estimates. However, if I use svyglm() from

survey package: proportion estimate confidence intervals using svymean
Using the survey package I find it is convenient and easy to get estimated
proportions using svymean, and their corresponding estimated standard
errors. But is there any elegant/simple way to calculate corresponding
confidence intervals for those proportions? Of course +/- 1.96 s.e. is a
reasonable approximation for a 95% CI, but (incorrectly) assumes symmetrical
distribution for a proportion.

SVY: variance inflation factor VIF with complex survey
Hello,
Seeking a way to get the variance inflation factor VIF for a model of regression in complex survey, I have understood that without this package (SURVEY) RGui VIF obtained as follows:
fit <- lm(mpg~disp+hp+wt+drat, data=mtcars)
vif(fit)
But I want to know if survey, Vif is obtained so
vif( svyglm(api00~ell+meals+mobility, design=dstrat))

Comparison of means in survey package
Dear list colleagues,
I'm trying to come up with a test question for undergraduates to illustrate comparison of means from a complex survey design. The data for the example looks roughly like this:
